نوع پژوهش	مقاله چاپ‌شده در مجلات علمی
کلیدواژه‌ها	ECAE- Flow lines- Back pressure- Plastic deformation
چکیده	Flow lines were analysed in aluminium alloy 6061 during equal channel angular extrusion (ECAE) in a 90 die with and without the application of back pressure during pressing. The lines appeared much more rounded when a back pressure was applied compared to the case of conventional ECAE testing. With the help of an analytic flow function, the deformation field was obtained. It is shown that back pressure slightly lowers the total strain, strongly increases the size of the plastic zone and significantly reduces the plastic strain rate.
